2.3 Hardware Setup
1. Connect the ADC3669EVM to the TSW1418EVM via the FMC connectors.
2. Connect the USB Mini-B connector (J5) on the ADC3669EVM to your PC using the USB Mini-B Cable
provided in the EVM kit. The AD3669EVM is powered via USB, so there is no need to provide external
power.
3. Connect the USB Mini-B connector (J2) on the TSW1418EVM to your PC using the USB Mini-B cable
provided in the EVM kit.
4. Make sure the PWR SEL headers (J10 & J13) on the TSW1418EVM have jumpers installed as followed:
This configures the TSW1418EVM for power via USB, so there is no need to provide external power.
5. Connect the Micro USB Cable to the JTAG dongle and connect the JTAG dongle to the JTAG header (J3) on
the TSW1418EVM. Then connect the Micro USB Cable to your PC.
6. Using an SMA cable and an inline 500MHz band pass filter, connect the signal generator to the SMA
connector labeled CLK (J3) on the ADC3669EVM. Set the signal generator's output signal frequency to
500MHz and the signal amplitude to +10dBm.
7. By default, the EVM is configured to take a single ended input, so analog inputs must be applied to
connectors AINp (J2) and BINp (J4) on the ADC3669EVM. Using an SMA cable and an inline 10MHz band
pass filter, connect the signal generator to analog input channel A (J2). Set the output signal frequency of the
signal generator to 10MHz and the signal amplitude to roughly +10dBm.
Figure 2-2 shows what the user's setup looks like.
